SAMUEL P. JACKSON, OF EAST LIVERPOOL, OHIO, ASS IGNOR TO HOMER LAUGHLIN, OF SAME PLACE.

MOLD OR OUTSIDE RING FOR POTTERY.

SPECIFICATION forming part of Letters Patent No. 406,350, dated July 2, 1889.

Application filed March 7, 1889. Serial No: 302,280. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL P. JACKSON, a citizen of the United States of America, residing at East Liverpool, in the county of Columbia and State of Ohio, have invented certain new and useful Improvements in Molds or Outside Rings for Pottery; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in the manufacture of pottery, the object of my invention being to provide means which are adapted to be secured to the revolving head orYlisk of a pottery-lathe, comprising aring, which is adapted to engage with a socket attached to the head of the lathe, so as to hold securely in place the mold upon which the article or dish is formed, as will be hereinafter fully set forth.

I11 the accompanying drawings, Figures 1 and 2 are sectional views taken through diametrically-opposite points, Fig. 1 showing the mold slightly elevated above the revolving head of the lathe. Fig. 3 is a plan view of the revolving head with a permanent ring attached thereto. Fig. 4 is a plan view of the removable ring. Fig. 5 is a sectional view of the same.

A refers to the whirling table or head of an oval lathe, which is rotated in the usual manner. This head has attached thereto a'socket-bed B, the walls thereof being raised or tapered, and at a suitable point upon the exterior wall this socket-bed is provided with a projection b, and has also formed therewith extensions 6 by means of which it is attached to the head A. The upper edge of this socket-bed has an indicating-notch 5 formed in the same, the notch 11 and projection Z) being of any suitable configuration.

Orefers to a removable ring, which is constructed to fit snugly over the socket-bed B, and it may be provided with recesses c and 0 which register with the projection Z) and notch 12 of the socket-bed. The base is cut away to provide space in which the projections 1) of the socket-bed will lie.

It will be observed that the exterior walls of the socket-bed taper, and that the interior walls of the ring C also taper, so that when the ring is placed on the socket-bed the parts will be immovably connected and will fit closely together. This is very desirable, especially where the parts are molded'in plaster.

Then the ring 0 is made of plaster, it may be provided with a metal band 0. At two diametrically-opposite points 9 the ring 0 is contracted or cut away, so that it will be of less diameter than the mold placed above the same. w

The mold D is preferably made of plaster, and the upper surface may be shaped to cor respond with the interior configuration of a dish, while the under side is projected downwardly, the exterior wall of which is tapered to lie within the inclined walls of the socketbed. yond the projection is shaped to correspond with the upper surface of thesocket-bed and ring. The under side of the mold may have recesses or projections, which will register with the projections or recesses formed in the ring and socket-bed.

The parts hereinbefore described may be made of any suitable material, as plaster, metal, or composition. The mold D is preferably made of plaster, while plaster is also preferred for the ring C.

It will be understood that the mold D is of proper shape to construct the article desired thereon, and that after the outside of the dish, plate, or other object has been formed the mold and ware are removed to the dryingroom. The shape of the mold is immaterial, as Well as the shape of the ring and socket bed, and the oval form is shown merely for the purpose of illustration, as it is the preferred form and one adapted to be used in connection with an oval lathe or jigger.

The ring 0 is cut away at 6, so that the ends of the mold maybe readily grasped by the attendant in removing the same from the socket-bed.

In manufacturing different styles or sizes of The balance of the under surface bedishes or pottery-ware different sizes of rings 0 and molds D can be used upon the same head or parts A and B, and the parts are so constructed that when they are placed together they are practically immovable, thereby producing, pottery-ware much more uniform and with greater facility.

By means of the hereinbefore-described device the perinanently-attached head or ring is dispensed with, and several sizes of dishes can be made upon one machine without destroying or changing the permanent head or ring A and 13.

Having thus described my invention, what I claim as new, and d esire to sc care by Letters Patent, is-

1. In combination with alathe head or table, a socket-bed attached thereto and provided with raised walls, a removable ring adapted to encircle the socket-bed and form a continuation thereof, and a mold constructed to have a bearing in and on the socket-bed and upon the removable ring, substantially as shown,

and for the purpose set forth.

2. In combination with a head or rotary disk A, having a socket-bed attached thereto, a removable ring 0, having interior wall adapted to fit over the exterior wall of the socket-bed, said ring being cut away at opposite points to be of lcssdiameter than the mold, and a mold D, having" the base shaped to fit within the inner walls of the socket-bed and also bear upon the upper faces of said socketbed and ring, substantially as shown, and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

SAMUEL I. JACKSON.
